Hearing in Colour and Crochet

I have been thinking about designing my own knitting and crochet patterns recently. I used to have a lovely hand knitted hat which I lost. Since I knit now I'm going to design something similar since I can't find a pattern like it. I also want a crochet shrug and haven't seen one I really like so the obvious answer is to design one.
I got The Crochet Stitch Bible which should help with this as it has loads of stitch patterns, edgings, lace and blocks to choose from. It's a great reference book for any crocheter. I especially like that all the designs are done using crochet symbols which I find much easier to understand than written crochet instructions. Crochet is 3D so the symbols suit it much more than written instructions.
Anyway that was what I was thinking about this week. I was at Kraftwerk on saturday night and had a rather strange experience. I've always seen music as colours and shapes. But the other night I started seeing the music as crochet stitch symbols with colours. It was kinda strange and I've never seen music like that before. And before anyone gets any ideas, I wasn't drunk or under the influence of anything. I think it might be good to try listening to a song a load of times and see if I can write down what I see in crochet symbols and colours and then make it. Certain sounds to me always have certain colours and shapes. Like drums are usually brown and quite squiggly and guitars are spiky and sometimes green or yellow. It could be a pretty interesting project.
